Although the main function of putty is leveling, if only putty is applied, only half of the leveling work has been done, and the other half is also the half that determines the effect, which should be solved by grinding. This is also the main function of wall grinding.

In the process of putty scraping, it is inevitable that some minor defects will appear, such as the connection at the putty junction, the traces left by local putty scraping too thin or too thick, pinholes caused by water absorption on the wall, etc. these defects can also be solved by wall polishing.

The putty surface structure after overall polishing is more uniform and consistent, which can strengthen the performance effect of emulsion paint and avoid some problems that may be caused by the difference of surface structure (such as local color difference of color paint, etc.).
墻面打磨用什么工具戏喊?
What tools are used for wall grinding?
燈泡:為了能隨時(shí)觀察墻面平整度,打磨時(shí)署咸,無論白天黑夜躺沽,工人一般都要在手里拿著一個(gè)燈泡。燈泡的瓦數(shù)一般都在200瓦以上铜乱,這樣即使白天也能很好的觀察到墻面的平整情況满盔。
Light bulb: in order to observe the flatness of the wall at any time, workers generally hold a light bulb in their hands during grinding, day and night. The wattage of the bulb is generally more than 200 watts, so that the flatness of the wall can be well observed even during the day.
砂紙:打磨膩?zhàn)拥纳凹堖x擇是大家比較關(guān)心的問題,這里系統(tǒng)講一下馏舰。墻面打磨中常見的砂紙目數(shù)(每英寸的砂粒數(shù))有80嗡吸、120、180匠借、240覆霹、320、400胆快、600。其中80照菱、120可以歸為粗砂紙烁焙,180、240為中等耕赘,320以上為細(xì)砂紙骄蝇。砂紙過粗,容易導(dǎo)致出現(xiàn)劃痕操骡,砂紙過細(xì)九火,很難打磨得平整,所以墻面砂紙的選擇册招,并不是越粗越好岔激,也不是越細(xì)越好,而是與墻面膩?zhàn)酉嗥ヅ錇橐恕?/div>
Sandpaper: the choice of sandpaper for polishing putty is a matter of concern. Here is a systematic discussion. There are 80, 120, 180, 240, 320, 400 and 600 sand paper meshes (sand grains per inch) commonly used in wall grinding. Among them, 80 and 120 can be classified as coarse sandpaper, 180 and 240 are medium, and more than 320 are fine sandpaper. If the sandpaper is too thick, it is easy to cause scratches. If the sandpaper is too thin, it is difficult to polish it flat. Therefore, the choice of wall sandpaper is not the coarser the better, nor the finer the better, but should match with wall putty.
實(shí)際操作中是掰,首先要以能把平整度做好為目標(biāo)虑鼎,墻面打磨多用240、320先進(jìn)行試打键痛,如果打磨起來不是很吃力炫彩,可以把平整度做得很好,那就繼續(xù)絮短;如果感覺打磨很吃力江兢,那就換用低目數(shù)的粗砂紙?jiān)龠M(jìn)行試打污涤。在保證了墻面平整度的前提下,如果一遍使用了粗砂紙昙激,一般整體或局部還需要用細(xì)砂紙?jiān)俅蚰ヒ槐樘凸韵稚凹埩粝碌膭澓郏⑶易寜γ娓蛹?xì)致担戏。
In actual operation, first of all, we should aim to do a good job in flatness. Wall polishing is mostly used. 240 and 320 should be tested first. If it is not very difficult to polish, we can do a good job in flatness, then continue; If you find it difficult to polish, use low mesh coarse sandpaper for trial beating. On the premise of ensuring the flatness of the wall, if coarse sandpaper is used once, it is generally necessary to polish the whole or part with fine sandpaper again to eliminate the scratches left by coarse sandpaper and make the wall more detailed.
按膩?zhàn)淤|(zhì)量來說续疲。非耐水膩?zhàn)佑捎诒砻娼Y(jié)構(gòu)疏松,所以比較容易打磨堵生,一般都用240嘁梦、320或更高的砂紙來打,不過由于大多數(shù)非耐水膩?zhàn)淤|(zhì)量都比較差钾士,粉料本身的目數(shù)普遍較低滩蔼,所以即便用高目的砂紙打磨,也很難打出非常細(xì)致的感覺应揉。
According to the quality of putty. Due to the loose surface structure, the non water resistant putty is easy to polish. Generally, 240, 320 or higher sandpaper is used to polish it. However, because the quality of most non water resistant putty is relatively poor and the mesh of powder itself is generally low, it is difficult to polish it with High-Purpose sandpaper.
耐水膩?zhàn)颖砻娼Y(jié)構(gòu)相對(duì)牢固粥搓,打磨要比非耐水膩?zhàn)淤M(fèi)力很多,尤其是一些高強(qiáng)型的耐水膩?zhàn)优堤颍绻鹊侥佔(zhàn)油耆赏负笤俅蚰ケ畈秃芾щy了,這時(shí)候就需要先用粗砂紙把平整度做好低飒,然后再用細(xì)砂紙打二遍许昨,以求更好的效果。
The surface structure of water-resistant putty is relatively firm, and polishing is much more laborious than non water-resistant putty, especially some high-strength water-resistant putty. It is very difficult to polish until the putty is completely dry. At this time, it is necessary to do a good job of flatness with coarse sandpaper, and then hit it twice with fine sandpaper, so as to achieve better results.
